SerraGlaze Enhances Daylight in ZNE Office Complex

New Zero Net Energy Lease @ office complex Boulder Commons

I recently had the pleasure of interviewing Andy Bush, Principal at Morgan Creek Ventures and a visionary who, in concert with the Rocky Mountain Institute, designed a Zero Net Energy (ZNE) leasing structure. The net-zero lease model is a profound way of sharing the benefits between landlord and tenant while incentivising all to reduce operating costs.

Morgan Creek’s new commercial development Boulder Commons,  located in Boulder Junction, Colorado consists of two buildings totaling 100,000 square feet of professional office space, retail space, and community gathering flex space. Boulder Commons is the first large-scale multi-tenant ZNE designed building requiring every tenant to sign a Zero Net Energy lease.

“To move the needle in both energy use and occupant comfort, we need to be willing to embrace the new technologies,” per Andy. SerraLux was thrilled to participate in this ZNE project by installing SerraGlaze daylight redirecting window film–designed to bring more natural light inside contributing to the comfort and well-being of …Read full article 

Green Schools Brighten Up!

Daylighting In Schools
Schools continue to request installation of see-through SerraGlaze Daylight Redirecting Film* to naturally brighten the classroom while cutting glare. Studies show properly day-lit schools reap marked benefits for students by offering an healthier and more enjoyable learning environment:

  • Reduces absenteeism
  • More attentive and alert students
  • Improves test scores
  • Increases vitamin D fostering student growth and health
  • Positive mood in students and lower noise levels

Daylighting does all this, while simultaneously saving energy and utility costs. Daylighting is one of the best investments you can make in the design of a learning environment.

Workplace Happiness with Natural Light

What makes you happy to get up and go to work each day? According to the Question & Retain (Q&R) Happiness in the Workplace Pulse Check, 40% of us say the most important factor that makes us happy at work is feeling valued and supported; 19% of us get out of bed for the intellectual challenge work provides; and for 12% of us  happiness is derived from pay and benefits.

However, it’s not just about the people, the job and the money; the data amassed by Leesman, the world’s largest independent assessor of workplace effectiveness, suggests that the physical work environment also plays a large role in boosting overall employee satisfaction levels. Having surveyed 250,000 employees worldwide, 85.1% state that the design of the workplace is important; yet only 56.7% of people feel the design of their workplace enables them to work productively.

A key workplace failure is the inappropriate provision of natural light. Of the quarter of a million employees in 69 countries surveyed by Leesman’s workplace benchmarking tool, 75.8% state that natural light is important to them, yet just over half are satisfied with the offering in their workplace. Meanwhile, research over the past few years from the International WELL Building Institute, Human Spaces and the World Green Building Council have all demonstrated the importance of natural light in employee engagement and productivity. And, Dodge Data and Analytics Smart Market Report found that “daylighting is currently the top strategy for improving occupant health.

How Can We Create a Happier Workplace?

When working in the confines of an office, an element of daylight is essential for employee well-being, engagement and productivity. A workplace infused with daylight and views to the outside can act as a buffer against the negative impact of job stress and positively impact general well-being. The research from Human Spaces, for example, demonstrated that proximity to natural elements, such as greenery and sunlight, was associated with a 15% increase in improved well-being and creativity, and 6% higher productivity.

Through building design, daylight can be maximized in a number of ways: building orientation, window design, configuration and glazing, strategic use of overhangs, and interior design and furnishings.  Nowadays, many companies place meeting rooms and cellular offices towards the middle of a building blueprint to allow natural light to flood the main office space where most people will be working.     

What Other Benefits are Gained by More Daylight?

Substantial energy savings can be achieved when businesses reduce the use of artificial light and instead harness the power of natural full-spectrum daylight. Integrating daylighting technologies in concert with lighting sensors that adjust electric lighting as needed, can further reduce energy consumption by up to 40-60%–a substantial improvement to the bottom line.

Workplace well-being has taken center stage in the world of work. As awareness around well-being grows so, too, will the awareness around daylight and its role in improving employee satisfaction levels while reducing our carbon footprint.

SerraLux Signs Contracts with Las Vegas Charter Schools

Press Release

SerraLux Signs Contracts with Las Vegas Charter Schools

SerraLux Inc., a leading global daylighting technology company with offices in the US and Europe, today announced that it had installed its daylight-distributing SerraGlaze window film in six Las Vegas charter schools. The move signals the start of the company’s expansion into the education space. The first five schools were completed in September 2015, and an additional school was completed in January 2016. SerraLux has also been asked to quote three additional Las Vegas schools.

School Children to Reap Benefits of Natural Light

Daylighting is the design of buildings to leverage natural light from the sun for interior illumination. SerraLux’s window film, SerraGlaze, redirects natural daylight to project it deeper into the room, reducing the need for artificial lighting, and cutting electricity bills. Increased natural light has been shown to improve student performance, well-being and overall levels of concentration.

A study by Heschong Mahone found that students in daylighted classrooms progress 20 percent faster on math tests and 26 percent faster on reading tests than students in classrooms with the least amount of daylight.

The first five schools were completed in September 2015 and an additional school in January 2016. SerraLux has also been asked to quote three additional Las Vegas schools.

If installed in all nine schools, SerraGlaze is expected to save the schools up to $60,000 in energy costs annually, 450,000 kilowatt hours in electricity usage annually, and 312 tons of carbon dioxide annually. SerraGlaze was specified by the schools’ architectural firm and a simple payback on energy savings is expected in less than five years.

Natural lighting is essential to a learning-conducive classroom environment 

Bob 2003“There is a growing consensus among all parts of the education industry — from architects to teachers — that natural lighting is essential to a healthy and productive classroom environment,” said Bob Ford, CEO, SerraLux. “Numerous studies have indicated that students learn faster and retain the learning longer when the classrooms have effective natural daylighting.

“SerraGlaze will pay for itself within five years through energy savings and thereafter the savings on electricity bills will be a welcome boost to school budgets. We are delighted to have worked with these forward-looking, dynamic Las Vegas schools. I’m proud that SerraLux has played a part in making their classrooms a more welcoming and learning-conducive environment for students.”

Daylighting – The Most Desirable Workplace Trait


info graph health and wellbeing no heading with top 10Daylighting is the practice of illuminating a building’s interior with natural light, distributing daylight, reducing glare and reflections, and controlling artificial light use. When daylighting is integrated with responsive dynamic lighting controls, there can be significant energy savings by reducing electric lighting loads.

Apart from energy savings, daylighting has been shown to improve performance and health of the occupants.  Studies show that daylighting synchronizes our circadian rhythms—our body’s “master clock”*–contributing to positive effects to our health and well-being. This internal body clock responds primarily to light and darkness in our environment, which is why humans are more alert while the sun is shining and are ready to sleep when it gets dark outside.

According to a recent survey of 1000 UK workers by the Royal Institute of Chartered Surveyors, ‘Lots of Natural Light’ was at the top of the list of desirable traits in the workplace, at 63%–interestingly far more important than ‘Good Security’ at 38%!  People feel better with natural light; they can see more clearly, colors are more vibrant, detailed tasks are easier and safer to perform, and there is a general feeling of exuberance working in a naturally lit and more comfortable environment.

Productivity of the staff or anything that influences one’s ability to be productive should be a major concern for any employer.  Natural lighting benefits may be fully realized if the daylighting design in the workplace is well balanced in quantity and quality.

300x300 P1010264b 2715x2717 tunedDaylighting technologies through windows has immense promise for both improved energy efficiency and the workplace environment. Our flagship product, SerraGlaze Daylight Redirecting Window Film converts incoming glare into beneficial daylighting by redirecting sunlight upwards (out of eyes) and deeper within a space.  The ceiling and walls diffuse this incoming light downward illuminating the work surfaces with full-spectrum daylight.  And, with the see-thru nature of SerraGlaze (see photo–>), the views are maintained out of the window and the building’s architectural aesthetics are preserved—another proven mental health benefit.

The use of naturally lighted spaces is a valuable strategy of earning LEED and BREEAM credits. Daylighting, properly done, saves energy, results in better occupant productivity/performance, and increases the building’s real estate value—truly a win-win-win!

Bringing Daylight into the Warehouse!

Daylighting dark spaces – providing better lighting helps occupants see better and work safer.

Daylighting is the design of buildings to leverage natural light from the sun for interior illumination. On average commercial buildings, electric lighting accounts for a staggering 35-50% of the total electrical energy consumption.  Many buildings can see total energy costs reduced by as much as one-third through the optimal integration of daylighting strategies.

The picture snapped is following the install of SerraGlaze Daylight Redirecting Film on the first of three windows in a warehouse.  Already there’s quite a bit of light (90% efficient) passing through up to the ceiling then diffused downward. Great natural lighting for those spaces which are usually 100% lit by electric lighting.  Employees have better light to work by making safer work conditions. The customer loves it!

Would you have warehouse that could benefit from free natural daylight?

“Intelligent Skins” Michael Wigginton on Daylighting in Building Design

Recently, we had the good fortune to interview University of Plymouth Professor Michael Wigginton, author of “Glass in Architecture” and “Intelligent Skins”, and a leading expert on building envelope engineering about the history and science behind sustainable building design and the integration of daylighting technologies.


SL: What do you understand and teach as the principal elements of sustainable architecture. Is the effective use of daylight essential to sustainable design?

MW: In the design algorithms I have developed, daylight has been an early morphological driver, because it enabled the building interior to be used optimally, exploiting the functioning of sight to operate in the spectrum it was evolved to use, without cost, except the cost of the window.  The removal of the requirement for artificial light except during the hours of darkness means that the lights can be turned off.  Conventionally lighting requires ~10 Watts per square metre.

SL: How do you view the value and importance of daylight in building design – offices, schools, hospitals and residences?

MW: I think it is fundamental.  It is what we have evolved to see by, and it is free. Quantification of value is hard in relation to some spheres, but all research supports the notion that our buildings should be day lit. Our eyes interpret colour best in daylight, and the whole spectral distribution inherent in the perception of form is properly interpreted.

SL:  What do you consider are the limiting factors on the use of daylight in architectural design?

MW: Daylight should be considered as a fundamental characteristic of building interiors, because the human system (and the eye) has evolved to respond to it.  The use of daylight was fundamental to all building design until the invention of electric light.  Windows make the interiors of buildings habitable. Unfortunately they also provide views of the sky which can be hundreds of time brighter than the interior, particularly in positions back from the window. The limiting factors are the ability of designers to enable daylight to reach building interiors whilst avoiding the problems of glare. The problem for design with daylight is the depth to which daylight extends to the interior, and the resulting large external wall: floor ratio, which opuses the cost of the external wall up.  This is why the search for light bending has been so important.

Are Healthcare Facilities Healthy?

269548_4087 free imageIt is quite amazing the vital force sunlight has on human health and well-being. We are just starting to understand the strong dependencies our bodies have on this natural, full-spectrum light. Interestingly, given this knowledge coupled with the critical role healthcare facilities play in our health and well-being; many of these facilities do not offer adequate beneficial daylight.

Powerful Health Benefits of Natural Light

The invention of the electric light bulb enabled the ability to construct buildings without concern of the orientation to the sun; the interior space could be lit artificially day or night. This seemed a great idea at the time. However we have recently learned a great deal about the physical, physiological, and psychological benefits of sunlight.

Studies suggest access to natural full-spectrum lighting from the sun is critical to optimal health and well-being. Our body’s circadian rhythm or master clock needs light to perform basic functions like sleeping or waking. And, “…sunlight actually increases levels of a natural antidepressant in the brain. On sunny days, the brain produces more of the mood-lifting chemical serotonin than on darker days,” writes Dr. Michael Murray for

In 2012, a revealing study about the ultraviolet-B (UVB) vitamin D connection to health, published in the Journal of Anticancer Research and based on data from over 100 countries, “consistently found strong inverse correlations with solar UVB for 15 types of cancer”, with additional evidence in the protective role of sunlight in 9 other types of cancer.  (Study by William B. Grant, Ph.D., Sunlight, Nutrition, and Health Research Center)

And, the sun plays a key role in recovery from injury or illness. “University of Pittsburgh researchers reported in 2005 that spinal surgery patients experienced less pain and stress and took fewer pain medications during their recoveries if they were exposed to natural light. An older study showed that the view out the window (trees vs. a brick wall) had an effect on patient recovery,” reports the Harvard Health Letter, July 2010.

Are Healthcare Facilities Healthy?

In the case of older healthcare facilities, many tend to feel like a maze of walls and corridors with curtains drawn or walls erected—electric lighting full on and daylight is shut out. Staff work round-the-clock and many times do not feel natural lighting nor experience the views outdoors for their entire shifts.

We have to remind ourselves that in healthcare facilities, it is not only the patients who benefit from a healthy daily dose of sunshine and views to the outside world, but staff as well. Without appropriate levels of natural light we do not see or feel as well and we are not as alert and vibrant—anyone is prone to become sickly, depressed or develop a general malaise. Is this how we want our loved ones to feel while trying to get well? Do we want their caregivers to feel and perform other than at their best? We need exposure to beneficial sunlight for the body to function well and feel good. Daylighting promotes healing and revitalizes patients and their caregivers.

Daylighting Plan

“Daylight through windows can comprehensively meet the whole of the visual, non-visual and perceptual requirements of the people living and working in built environments, clearly enlightening both the task and the internal spaces, and providing the conditions needed for health and well-being..” (Study by Sergio Altomonte, Daylight for Energy Savings and Psycho-Physiological Well-Being in Sustainable Built Environments).

An integrated daylight harvesting plan which includes beneficial daylight and view retaining window technologies, reflective ceilings, and daylight sensitive dimmable lights will provide a better indoor environment—better lighting and views—enhancing the health and well-being of all occupants.

Architecture Design Principles In Daylight Performance

Snapshot of Interview PDF

They are a lot of architectural design principles that play a role in obtaining optimum daylight performance in office buildings. In our e-book interview with daylighting expert Professor John Mardaljevic we asked him a couple of questions on how architects can use daylighting in their projects. For the full-interview, download our e-book.

SerraLux: Which architecture design principles are key in daylight performance of office buildings? 

JM: No simple answers here. The one recommendation I give is that architects familiarise themselves with the daylighting designs that appear to work well—and then try to determine what is it about the context and local climate that works with that particular solution. Because, the same solution—in a building with a different aspect or located in a different climate—may not work so well.

SerraLux: An understanding of colour rendering, the use of natural light, and its effect on works of art is critical for architects specializing in museums. Are those principles and practices carrying over into the practices of other architects?

Colour rendering is an issue if the interior space has non-neutral, fixed-tint glazing, or if highly saturated colours are used in the interior decor. The key concern appears to be the spectrum of illumination from artificial lighting, particularly LEDs. This has resulted in the emergence of a market for reliable and inexpensive handheld spectrometers to measure artificial light spectra in buildings tools that can also be used to measure the spectra of daylight illumination if required. So there is some crossover, yes.

Daylighting insights from Professor John Mardaljevic

John Mardaljevic

SerraLux was fortunate to interview Loughborough University Professor John Mardaljevic (@jmardaljevic on Twitter) on the history—and future—of daylighting. This blog shares a few brief excerpts from that session. To read the full interview this renowned daylighting expert, download the pdf.

SL: In terms of regulatory changes, and LEED and BREEAM specifications, what changes do you see in the next 3 years regarding the use of daylight in buildings?

JM: In 2013, the UK Education Funding Agency made CBDM a mandatory requirement for the evaluation of designs submitted for the Priority Schools Building Programme (PSBP). This is the first major upgrade to mandatory daylight requirements since the introduction of the daylight factor more than half a century ago. While perceived as long overdue in some quarters, in others the move controversial and is not without its critics.

SL: Historically, daylighting initiatives are often driven by a desire to save energy. What other adoption drivers of adoption are you seeing and how important are they?

JM: Without a doubt, energy saving is an important consideration. However, if that was the sole driver, we would not have windows at all. Instead, we would have super-insulated walls with LED lighting to provide illumination. We now appreciate that good daylighting has consequences for the long-term health, well-being, and productivity of building occupants. The non-visual effects of daylight illumination are believed to be of great importance for the maintenance of a healthy sleep-wake cycle, or circadian rhythm. The mechanisms are not fully understood, and it is not yet known what the preferred exposure levels should be. What’s not in doubt is the importance of providing daylight to building occupants, whether they be in offices, schools, hospitals, factories etc.

SL: Obviously, designers considering incorporating daylight design are looking at the metrics: the energy efficiency savings and the improvements to occupant’s performance. How can daylight simulation provide those metrics?

JM: The question of daylight metrics is a “hot topic.” Anyone who wishes to promote daylight where there is an associated cost is, in effect, “selling” daylight. When attempting to sell any commodity where the supply cannot be guaranteed at a steady rate, the first two questions asked by a potential purchaser are: How much of it will I get? And how often will that occur? Two such metrics are daylight autonomy (DA) and useful daylight luminance (UDI). I personally favour UDI because it gives an indication of the degree to which an upper threshold for illuminance.
